Nautilus Shells 7”+ Pearl Chambered clam Their nervous ganglia are concentratedNautilus have a well developed nervous system and highly developed eyes. Surrounding the mouth are many tentacles. Nautilus are the only cephalopod to have a true external shell. Naturalists, mathematicians and physicists have been fascinated for years by the form of this shell. The spirally coiled, chambered shell is perfectly proportioned mathematically, a remarkable feat of natural engineering. Air is moved through the many chambers to control
